Conservation

Conservation DecliningFranklin's Gull populations declined throughout their range by almost 3% per year between 1966 and 2015, resulting in a cumulative decline of 78% according to the North American Breeding Bird Survey. In the U.S., declines were over 6% per year during that same period, which amounts to a 96% decline. The North American Waterbird Conservation Plan estimates between 315,608-990,864 continental breeding birds and lists it as a Species of Moderate Concern. The species rates an 11 out of 20 on the Continental Concern Score. Franklin's Gull is listed as Common Bird in Steep Decline on the 2014 State of the Birds Report, but is not on the 2016 State of North America's Birds Watch List. These birds depend on extensive prairie marshes for breeding, and entire colonies may shift sites from year to year depending on water levels. Once threatened by habitat loss due to large-scale drainage projects and the Dust Bowl years of the 1930s, this species has regained numbers with the creation of large wetlands, mainly on protected national wildlife refuges. Colony shifts continue to occur, however, influenced by drought and fluctuating water levels.Back to top
